"Nepenthes fallax" (pronEng|nəˈpɛnθiːz ˈfælæks, from Latin: "fallax" = spurious, not genuine) is a tropical pitcher plant endemic to Borneo. It produces attractive funnel-shaped pitchers up to 15 cm high.Clarke, C.M. 1997. "Nepenthes of Borneo". Natural History Publications (Borneo), Kota Kinabalu.]

There has been confusion surrounding this taxon and "N. stenophylla" ever since it was first described. "N. fallax" matches "N. stenophylla" in most respects, except for the shape of the lid; the type specimen of "N. fallax" has an lid, whereas that of "N. stenophylla" is narrow. However, the description of "N. stenophylla" was based on a plant raised from seed in a greenhouse in England, and the shape of the lid could be an aberrant characteristic resulting from artificial growing conditions.

In his seminal monograph "The Nepenthaceae of the Netherlands Indies", B. H. Danser treated "N. fallax" as a junior synonym of "N. stenophylla".Danser, B.H. 1928. The Nepenthaceae of the Netherlands Indies. "Bulletin de Jardin de Botanique, Buitenzorg", Série III, 9(3–4): 249–438.] This interpretation was supported by a number of subsequent authors.Jebb, M.H.P. & M.R. Cheek 1997. A Skeletal Revision of "Nepenthes" (Nepenthaceae). "Blumea" 42(1): 1–106.]

Jan Schlauer, however, considers the taxa as two separate species based on the shape of the lid. [Schlauer, J. 2006. [http://www.omnisterra.com/bot/cp_home.cgi?name=Nepenthes+fallax&submit=Submit+Query&search=all "Nepenthes fallax"] . Carnivorous Plant Database.]
